Critical Thinking

  • Anchoring bias: The tendency to rely too heavily on the first piece of information encountered when making decisions.
  • Strawman fallacy: Misrepresenting someone’s argument to make it easier to attack.

Together we’ll make a project where, from a remote control, you can send commands to the car’s micro:bit. Not with tilting, like before, but by selecting a command and then touching the logo.

Remote Control

  • Use A and B to select which command to send. Make up your own commands, such as:
    • Go forward and then back
    • make a small circle
    • make a large circle
    • turn on the lights
  • Show the selected command on the LEDs, using one of the show string, show number, show leds, or show icon blocks
  • Touch the logo to send the selected command

The Car

  • Use the radio blocks to receive the command
  • Determine which command was sent and execute it

Hasty Generalization

An example from ChatGPT:

Imagine a student named Sarah who tries eating a new vegetable for the first time, like broccoli. She doesn’t like it at all. Then, she says, “I hate all vegetables!”

This is a hasty generalization because Sarah only tried one vegetable but made a quick decision about all vegetables without trying others like carrots, corn, or cucumbers. Just because she didn’t like broccoli doesn’t mean she won’t like other veggies.

The discovery of tools key to machine learning wins the 2024 physics Nobel

Perplexity.ai created an explanation:

The 2024 Nobel Prize in Physics was recently awarded to two scientists, John Hopfield and Geoffrey Hinton, for their important work in machine learning and artificial intelligence (AI). What did they do? These scientists used ideas from physics to create new ways for computers to learn and solve problems, kind of like how our brains work. They developed something called “artificial neural networks,” which are special computer systems that can recognize patterns and learn from data. Why is this important?

Their work has helped make computers much smarter and able to do amazing things like:

  • Understand and translate languages
  • Recognize faces and objects in pictures
  • Help doctors diagnose diseases
  • Drive cars without human drivers

These discoveries have changed many areas of science and our everyday lives.

Who are the winners?

  • John Hopfield: He’s a professor at Princeton University in the United States.
  • Geoffrey Hinton: He’s a professor at the University of Toronto in Canada. Both scientists will share the prize money of about $1 million. This Nobel Prize shows how important artificial intelligence and machine learning have become in our world. The work of Hopfield and Hinton has opened up new ways for computers to help us solve complex problems and make exciting discoveries in the future.

Critical Thinking

Loaded Question Fallacy (as explained by ChatGPT)

A loaded question fallacy is when someone asks a question that makes you look bad or guilty, no matter how you answer. The question assumes something that may not be true, which can trick the person being asked.

For example, if someone asks, “Why are you always late to class?” this assumes that you are always late, even if that’s not true. If you try to answer it, you’re stuck defending yourself instead of talking about whether you’re late or not.

To avoid falling into the trap, you can point out the assumption in the question and say something like, “I’m not always late to class.” This way, you’re challenging the assumption instead of just answering it.

Dunning-Kruger Effect (as explained by ChatGPT)

The Dunning-Kruger effect is when people who know a little bit about something think they know a lot more than they really do. It’s like when someone is new to a skill but doesn’t yet realize how much more there is to learn.

For example, imagine a person who has just started learning how to play chess. After winning a few games, they might think they’re really good at it, but they don’t yet know all the strategies or how complicated the game can get. This effect happens because, when we’re just starting out, we don’t always know enough to see what we don’t know!

As we learn more, we start to see the bigger picture and realize how much more there is to learn.

Python (again, thanks to ChatGPT for the introduction)

Python is a popular and easy-to-learn programming language that powers many things in the real world. From video games and websites to robots and apps, Python is behind many of the cool things we use today!

Why Learn Python?

  • Simple & Fun: Python looks like English, making it easier to understand and write than many other languages.
  • Create Anything: With Python, you can build video games, create apps, or even control robots. Imagine coding your own game or creating a website!
  • Real-World Power: Big companies like Google, YouTube, and Netflix use Python because it’s powerful and versatile.

Cool Projects You Can Do with Python:

  • Make a Simple Game: Ever played games like “Guess the Number”? You can write your own with just a few lines of Python.
  • Control Robots: Using Python, you can program robots or devices like micro:bits (which we use in class!) to perform tasks and solve problems.
  • Solve Problems & Be Creative: Coding with Python helps you think logically, solve puzzles, and bring your creative ideas to life!
